President Obama signed a bill Sunday to fund health benefits for 9/11 relief workers.

The James Zadroga 9/11 Health and Compensation Act — which gained its namesake from the first NYPD official to lose his life following health complications attributed to toxic chemicals at New York's Ground Zero site — passed Congress just before lawmakers left for the holiday break.

"I was honored to sign the James Zadroga 9/11 Health and Compensation Act to ensure that rescue and recovery workers, residents, students, and others suffering from health consequences related to the World Trade Center disaster have access to the medical monitoring and treatment they need," Obama said in a statement.

"We will never forget the selfless courage demonstrated by the firefighters, police officers, and first responders who risked their lives to save others," he said. "I believe this is a critical step for those who continue to bear the physical scars of those attacks."
